To aZZ whom. ii, may, concern:

Be it known that I, HANS CHRSTIAN LUNGE, a subJect of the King of Denmark, residing at Soro, in the Kingdom ofI Denmark, have invented certain new and useful Improvements in Boiler-Feeders; and-I dohereby de'- clare the following to be afull, clear, and eX- act description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. My invention relates to devices for supply- 1ng feed water to steam boilers and has especial reference to that class of boiler feeders that are automatically operated and regulated by the height of the water level within the boiler. My invention consists .generally in employing a reservoir.V in communication With the boiler by a continuously acting feed pump or injector and having devices toautomatically regulate the introduction of water into the said reservoir.

In the accompanying drawings I show the preferable form of my device.

.Figure l is a front view of the device. Fig. 2 1s a side view of a part` of the same: Fig. 3 is a sectional view taken on the line xof Fig. 2, and Fig. 4 is a sectional view taken f on the line y-y of Fig. 3.

In all the above views corresponding parts are designated by thegsame letters of reference.

c, is a steam boiler which is connected with the horizontal cylinder 7L, by means of the fn, to permit the cylinder to Yturn freely and still provide a steam .tight joint.Vv The ncylinder his mounted within a bearing Z, formed integral with the casting o', and is free to revolve therein. Secured to the cylinder h, at rightangles to the pipe m, is another pipe d, which connects with the receiver k, shown spherical in shape, and is provided with a Water gage k. On the opposite side of the cylinder h is an arm e, upon which is mounted the counterbalancing weight j", capable of proper adj ustment.

Near one extremity of the cylinder h is vformed a cam piece e (Fig. 4) which engages serial no. 503,330. (Nb model.;

with a vroller 0,1nounted'within the bifurcated portiong of the valve stem o2, which in turn supports the valve o, which is of an umbrella or mush-room shape and rests upon the valve seat o', preferably removable and adapted to be replaced in event of wear.

r, is Aa waterpipe connected with the source of supply at nominal pressure. r" is the exit pipe for the water in the boiler and which connects with the feed pump r4 which is operated by the steam from the boiler through the pipe r3." c, isa cup-shape reserabove the opening of the pipe m, the pressure of the steam will force water into the pipe m, cylinder h, and tubed, and Will completely or partially fill the receiver lo against the pressure of the atmosphere, as will be indicated upon the glass 7c. This will cause the parts to assume the positionshown in Fig. 2, with the valve o, firmly set upon its base and preventing the entrance of water tothe receiver. Upon the water line being lowered by the evaporation of the water from the boi1e`r,thepopening of the pipe lm will be eX- posed, the pressureof the steam will displace the water Wholly or in part Within the receiver 7c. This will lighten the receiver and will cause-it to be elevated by the action of the counter balancing weight f. By this mOYQIILent the cylinder h will be partially rotated and the cam portion e acting upon the roller o, will allow the valve o, to be elevated by the pressure of the Water within the column c. Water will n'ow flow into the reservoir and from there will be pumped into the boiler roo the valve o, and prevent the further admission of water to the reservoir and thence to the boiler.

In order to facilitate the operation of the apparatus I preferably make use of an addi tional pipe m', which connects with the cylinder h by means of the stuffing box n upon the opposite side from the entrance of the pipe m. This pipe m communicates with the receiver k by means of a pipe u, the par tition s, preventing communication between the two ends of the cylinder h. The lower opening of the pipe m is considerably lower than that of the pipe m, and will always be immersed within the water of the boiler.

The operation of the modification is substantially the same as described. When the water is at the proper height, both pipes m and m will be filled with water but upon the lowering of the water in the boiler the extremity of the pipe m will become exposed, which will free the parts of the water contained therein through the pressure of the steam upon the water contained within the` pipe m.

While I have described my invention as used in connection with steam boilers, I do not desire to be limited to such connection,as my device can be employed as well for feeding liquids to vessels containing the liquid and a gas under pressure, as for instance, in the handling of various fermented liquors under pressure; to soda water and for other purposes.

Having now described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

l. In a feeding device for steam boilers, the combination of the reservoir c, connected with the feed pump or equivalent element, a valve fu, for controlling the supply of water to said reservoir; an oscillating cylinder 7L, mounted above said valve and adapted to open and close the same, a receiver k, connected with said cylinder by a pipe d, the counter-balancing weight connected with said cylinder at the other side thereof by a lever arm e, and a pipe m, extending from within the boiler and connected with said cylinder h, and communicating with said receiver la, substantially as described.

2. In a feeding device for steam boilers, the combination of a reservoir c, connected with the feed pump or equivalent device, a valve o, for controlling the supply of water for said reservoir, an oscillating cylinder h, mounted above said valve and adapted to open and close the same, a partition in said cylinder for dividing the interior thereof into two parts, pipes fm, and m', extending from within the boiler at different levels, and leading into the respective ends of said cylinder, a tube d,ex tending out from said cylinder and communicating with one of its parts, a receiver 7c, carried by said tube d, and communicating with the same, a pipe u, connecting the other part of the cylinder with said receiver opposite to the pipe d, and a counter-balancing weight f, ou the lever e, substantially as described.

3. In a feeding device for steam boilers, the combination of a reservoir c, connected with the feed pump or equivalent device, a hollow column c in said reservoir connected with the water supply, a valve at the top of said column c', acylinder h, mounted above said valve and adapted to open and close the same, a pipe m, extending from within the boiler and connected with the interior of said cylinder, a pipe CZ, extending out from said cylinder, a receiver 7c, carried by said pipe and communicating with the interior of the boiler by means of the pipe d, cylinder h, and pipe m, and a counter-balancing weight f, secured to a lever arm c, for counter-balancing the receiver 7a, substantially as described.

4. In a feeding device for steam boilers, the combination of the receiver c, connected with the feed pump or equivalent device, a hollow column c' within said receiver and connected with the water supply, a valve v, at the top of said column and provided at its upper end with a roller o, an oscillating cylinder 7L, mounted above said valve, a cam c on said cylinder engaging with said roller o, a pipe m, 9

extending from the interior of the boiler, and connected with the interior of said cylinder, a pipe d, extending out from said cylinder, a receiver k, on the end of said pipe and communicating with the interior of the boiler by means of a pipe d, cylinder h, and pipe m, and a counter-balancing weight f, for counterbalancing said receiver, substantially as described.

This specification signed and witnessed the 23d day of December, 1893.
